Time evolution of angular velocity (Omega) in 2D hydrodynamics simulation

2D hydrodynamics simulation to be compared to 1D stellar evolution model. In both 1D and 2D, the instability develops within an hour around radius, r=1.3e9 cm. We can see how the instability spreads out the initially steep omega gradient. Results will be published in Edelmann et al 2016 (in prep.)
